摘要
通过矩阵刻画粗糙集理论,用模糊矩阵定义了模糊粗糙集的上(下)近似、重要度等概念,给出模糊决策系统的属性约简算法.将其运用到信息系统的属性约简算法和模糊信息系统的属性约简算法中,用UCI数据集说明算法的可行性.
Abstact:The rough set theory is characterized by the matrix .According to the fuzzy informa‐tion systems and fuzzy decision system ,the relative concepts of fuzzy rough sets and rough fuzzy sets such as ,upper (lower) approximation operator etc .are defined by fuzzy matrix ,and the attribute reduction algorithms on them are given .Moreover ,the feasibility of the algorithm are verified by UCI sets .
